'02 4Runner_U (L/O 0108) D You may feel vibration or noise in your vehicle, caused by operation of the brakes. This indicates the system is functioning properly. The slip indicator light comes on for a few seconds when the ignition key is turned to "ON". If the indicator light does not come on when the ignition is turned on, contact your Toyota dealer. "VSC TRAC" warning light This light warns that there is a problem somewhere in the active traction control system or the vehicle skid control system. The light will come on when the ignition key is turned to "ON", and will go off after about a few seconds. The light may come on for 60 seconds after the ignition key is turned to the "ON" position. It is normal if they go out after a while. Depressing the brake pedal repeatedly may turn on the light. It is normal if it goes out after a few seconds. The brake actuator temperature increases during continuous operation of the active traction control system or vehicle skid control system such as on slippery roads. If the brake actuator temperature becomes too high while the active traction control system or vehicle skid control system is operating, a buzzer will start to sound intermittently to indicate that the active traction control system can no longer operate. In this case, immediately stop your vehicle at a safe place. If the system continues to operate, the buzzer sound changes from intermittent to continuous. (The continuous buzzer sounds for about 3 seconds.) At the time, the "VSC TRAC" warning light will come on and the active traction control system temporarily stops operating in order to protect the brake actuator. (Although the active traction control system does not operate, there is no problem to continue your driving.) The system will be automatically restored after a short time and the "VSC TRAC" warning light goes out. 2002 MY 4RUNNER_U (OM35787U) 123
